当与其他用户登录时，它仍然从无处选择以前的用户 uuid

Question

我正在处理我的一些项目，我面临的问题是当我使用用户 "A" 登录并使用该应用程序一段时间后，我注销该用户，然后我使用另一个用户登录 "B" 然后在我必须显示用户个人资料图片的某些屏幕中（基础 url + 个人资料图片名称）。它没有显示，当我记录个人资料图片 url 然后我发现它仍在获取旧登录用户的 uuid "A".

注意：- BaseUrl 由 uuid 串联而成。

这是登录和注销方法 classes 和常量 class，我用它来保存登录响应的数据，并清除注销响应的数据

状态为1时的登录方式:-

                        if(status == 1)
                        {
                            DispatchQueue.main.async {

                                UserDefaults.standard.set(self.DataDict, forKey:MaindataKey)
                                let Dict = self.mainDict[KData] as!  [String: AnyObject]
                                print("self.DataDict", self.DataDict)
                                let User_ID = Dict[KUuid]as! String
                                print(User_ID)

                                self.navigationController?.pushViewController(tabar, animated: true)

                            }

状态为 1 时的注销方法:-

                    if(status == 1)

我认为问题是由线程引起的。从主调度队列中移动非 uikit 类操作。

状态为1时的登录方式:-

if(status == 1)
    {
        UserDefaults.standard.set(self.DataDict, forKey:MaindataKey)
        let Dict = self.mainDict[KData] as!  [String: AnyObject]
        print("self.DataDict", self.DataDict)
        let User_ID = Dict[KUuid]as! String
        print(User_ID)
        let HMACSECRETKEY = self.deviceToken + "+" + User_ID
        kHMACKey = HMACSECRETKEY
        let cipher:String = CryptoHelper.encrypt(input:HMACSECRETKEY)!;
        print(HMACSECRETKEY)
        UserDefaults.standard.setValue(cipher, forKey:HmacKey)
        UserDefaults.standard.set(true, forKey: "isLogin")
        GAloginUserInfo.shared.saveUserInfo(dict: Dict )


        DispatchQueue.main.async {
            GAReusableClass.sharedInstance.hideActivityIndicator()
            let tabar = self.storyboard?.instantiateViewController(withIdentifier: "GAtHomeTabbarViewController") as! GAtHomeTabbarViewController
            self.navigationController?.pushViewController(tabar, animated: true)

        }
    }

状态为 1 时的注销方法:-

if(status == 1)
    {
        defaults.removeObject(forKey: MaindataKey)
        defaults.removeObject(forKey: HmacKey)
        defaults.set(false, forKey: "isLogin")
        GAloginUserInfo.shared.removeUserInfo()

        DispatchQueue.main.async {
            GAReusableClass.sharedInstance.hideActivityIndicator()

            let login = self.storyboard?.instantiateViewController(withIdentifier: "GALoginViewController") as! GALoginViewController
            self.navigationController?.pushViewController(login, animated: true)

        }
    }

我认为当你注销时 UIKit 会保留一些值，要删除它，当您注销时，您应该清除所有 View 控制器，这样您的所有 UIKit 数据将被删除并且您的问题得到解决。如果您的注销 API 状态为 1，请输入此代码。

let toViewController = mainStoryboard.instantiateViewController(withIdentifier: "KSLoginViewController") as! KSLoginViewController// Login view controller here
                                    let fromView = UIApplication.shared.keyWindow!.rootViewController!.view
                                    UIApplication.shared.keyWindow?.rootViewController = toViewController
                                    
                                    let toView = toViewController.view
                                    toView?.addSubview(fromView!)
                                    
                                    UIView.animate(withDuration: 0.38, delay: 0.2, options: [], animations: {
                                        fromView?.transform = CGAffineTransform(translationX: -UIScreen.main.bounds.width, y: 0)
                                    }, completion: { finished in
                                        fromView?.removeFromSuperview()
                                    })

注销后，当您尝试在登录后推送另一个视图控制器时使用此代码。

let teacher = studentStoryboard.instantiateViewController(withIdentifier: "KSStudentDashboardVC") as! KSStudentDashboardVC
                                        let aObjNavi = UINavigationController(rootViewController: teacher)
                                        let appDelegate: AppDelegate = (UIApplication.shared.delegate as? AppDelegate)!
                                        appDelegate.window?.rootViewController = aObjNavi

当与其他用户登录时，它仍然从无处选择以前的用户 uuid

When login with other user it still picks previous user uuid from nowhere

swift

logout
